To all whom it may concern: I

Be it known that I, BRUNO RGMER, a subject of the Emperor of Germany,residing at Siegmar, Saxony, in the German Empire, have made certain.new and useful Improvements in or Applicable to Machines Used inApplying Strips of Paper or Cloth to Boxes of Cardboard and the Like, ofwhich the following is a specification.

The invention has been patented in Germany, No. 87,140, dated June 28,1895; in England, No. 243, dated January 4, 1896; in Italy, No. 152,dated November 12, 1895; in Austria, No. 4,605, dated December 2, 1895;in Belgium, No. 11,835, dated November 30, 1895; in Spain, No. 18,247,dated February 13, 1896, and in France, No. 251,301, dated February 11,1896.

My invention relates to improvements in machines or appliances used forapplying strips of paper to boxes or box-lids made of cardboard or thelike materials.

In the accompanying drawings, Figure l is a sectional elevation of themachine; Fig. 2, a front view; Fig. 3, a side elevation, and Figs. 4 to10 show details.

The machine is constructed in the following manner: The strip 00 iswound in a flat state on a roller a, Fig. 1, whence it runs to thefolding apparatus 5, in passing through which the strip is bentangularly or round, and thereby acquires greater resistance todeflection.

The details of the folding apparatus are shown in Figs. 4 and 5. Thestrip passes through a semicircular funnel b, terminating in a slot. Infront of the slot are two rollers 19 11 The strip is thus folded orpartly broken in half and adapted for use on boxes with sharp corners,for which the folding in half particularly fits it, inasmuch as thecorners are thereby rendered clean and sharp and the strip does not getcrooked on the corners. Further, the effect of the partial breaking ofthe strip is that the strip gets a set which causes it to tend to assumethe folded shape and not to spring away from the corner as is usuallythe case when the strip is pasted flat.

For round boxes or boxes with rounded corners the folding appliances maytake the form of a tube, as shown at b in Fig. 6. The feed end may inthis case be shaped as shown in profile at b and the delivery end asshown at b. Other suitable shapes may be adopted for the delivery end ofthe tube b according to the shape of the object to which the strip is tobe applied.

The folding device is usually applied in or to the pasting-machineitself, but the strips may nevertheless be drawn through the foldingdevice placed outside the machine. Behind the folding device b, Fig. 1,is placed the feeding apparatus consisting of two rolls If the strip isintended for usein a partly-doubled state for a box with sharp corners,the contact-surfaces of the feed-rolls 0 cl are angular incross-section. (See Fig. 9.) If, on the other hand, the strip is for around box or a box with rounded corners, the profiles of the rollers adare modified accordingly. The lower roll (Z runs in a receptacle 6,containing a suitable adhesive preparation or water, as the case mayrequire.

The strip is pushed by the feed-rolls through an aperture in the part f(of a shape corresponding to the part of the box to which the strip isto be applied) and under the die g. Owing to the rigidity imparted bythe folding operation, the strip does not deviate from its horizontalposition and may be pushed forward with accuracy and certainty.

The descending die 6, which presses the strip on the box, at the sametime cuts off the required length from the continuous strip. To effectthis, the die works quite close to the part f. so that the die g and thepart f together form a guillotine or shears.

The boxes y which are operated on are placed on a support or table m,Fig. 2, the upper part of which has the same profile as the corner orother part of the box resting thereon. The table m is longitudinallyadjustable in order totake boxes of different depths.

I11 order that the length of strip to be used may be varied tocorrespond, the feed-rollers are driven in the following manner: Theshaft d of the lower feed-roll carries a ratchetwheel 61 Fig. 9, withwhich engages a pawl 0Z Fig. 10, mounted on a spL1r-wheelcZ ,which isfree to revolve about the ratchet-wheel d so that if the wheel 01 iscaused to rotate backward and forward the shaft d is only taken in onedirection. Gearing with the wheel (7 is an oscillating toothed sector p,Fig. 3, having the arm p. This arm is eon neeted to the arm 7; of athree-armed lever by an adjustable fork n, adjustably secured to the arm7& and engaging with its fork a pin '72 on the arm 1').

According to the position of the fork a, (which can beaceurately set bymeans of an index,) the armp, and with it the toothed sector p,oscillates through a greater or less angle. The lever 7L, which operatesthe die 7, is driven by the three-armed lever 7n 752 711, having itsfulcrum at 7;, by means of a roller 71 mounted on the lever 71, takinginto a slot i in the arm 711 To the arm 7" is attached a rod 71;, whichis connected at its lower end to a treadle. On the descent of the latterthe lever 7. 7.? 75 turns to the left the toothed sector, and therebythe feed-rolls are first actuated so as to push the strip forward. Thenthe die 1 descends, cutting off the strip and pressing it onto the box.On the release of the treadle the resilience of the spring 75 bringsback the lever 7t" 75 75 and with it the lever 71, while the die rises,and at the same time the sector 1 goes back to its first positionwithout turning the feed-rolls.

Having thus described my invention, what I claim is 1. In combination,the paper roller, the feed-roller and the crcaser comprising the guide7) and the rollers 71 7)" adjacent thereto.

2. In combination, the paper-roller, the feed-rollers, the creaserdevice, said teed-rollers having their peripheries conforn'iing to thecrease of the paper, the reciprocating die, the pawl and ratchet for thefeed-rollers, the oscillating segment with the gear for operating theratchet, the lever 70 for operating the die and the three-armed leverwith connections therefrom to the lever 7t and the oscillating segment,substantially as described.

In testimony whereof I have hereto set mv hand in the presence of thetwo subscribing witnesses.

BRUNO HOMER.
